Abstract: A method for generating digital imaging data for an imaging unit, in which digital imaging data are defined from a signature of input image data, in that a section of the signature corresponding to the imaging format of the imaging unit is processed (24) into a raster image by a raster image processor, the section being defined on the basis of geometric parameters of an image area of the input image data. A raster image processor for implementing the method includes a raster-image-processor program having at least one section, in which geometric parameters for defining the section to be processed, are assigned (16) to input variables for the rasterization.

Abstract: A book scanner for scanning a book having first and second inner surfaces and a ridge. The scanner includes a transparent platen for supporting the first inner surface, a housing, and a scanning module. The housing has a housing platen for supporting the second inner surface, and the housing and transparent platen are connected to define a first angle smaller than 180 degrees. The module is moved along a direction parallel to the ridge to scan the first inner surface. The module includes a lighting device having first and second sections. The two sections define a second angle smaller than 180 degrees; and the second section has a second end, and a first end closer to a first plane containing the transparent platen than the second end. The bent second section may provide extra light rays to compensate the brightness and thus enhance the edge image quality.

Abstract: A targeting device suitable for mounting an optical scanner includes a frame, a linkage slidably mounted on the frame, an actuator arm secured to the linkage, which actuator arm has an outer surface configured to slidingly engage the surface of the object to be scanned and a holder mounted on such that the actuator arm moves in tandem with the linkage along the frame when the object to be scanned is inserted between the actuator arm and a support surface below the actuator arm so that an optical scanner in the holder is held at a predetermined scanning distance from the object to be scanned.

Abstract: An apparatus for creating an ICC profile in a simple manner without using a specialized measuring instrument. A display control unit reads out a dot pattern image from a pattern image data holding unit and a grayscale pattern image containing a plurality of grayscale patches of gradually varying gray scale from a grayscale image data holding unit, and presents the thus readout images for display on a display device. A user selects the grayscale patch having brightness closest to the brightness of the dot pattern image by operating a selection unit. Based on the selection, a gamma coefficient value is calculated by a gamma coefficient value calculation unit, and based on this gamma coefficient value, a profile creation unit modifies the ICC profile held in a common information holding unit and thus creates a customized ICC profile.

Abstract: A method for generating printed images of a graphic pattern of a movie picture to be displayed for moving observers using a long display panel composed of the graphic pattern and a plate made up of a plurality of cylinder converging lenses arranged parallel to each other with a common focal plane. A digital storage device able to store a plurality of data or digital information blocks, corresponding to the images to be exhibited, for example, the sequence of frames of a movie picture encoded in a digital format is provided. Each block has a label that determines its correlative order in the set. A digital processing unit and memory, able to call, read and process the digital data blocks, is provided that can also create and send to the storage device new data blocks, or byte arrays, containing the graphical patterns in digital format.

Abstract: An image reading apparatus according to the present invention employs an optical system including a fluorescent lamp as a line light source for illumination of the image source. An image reader housing has an elongated window. The translucent lamp positioned within the housing has a light emitting tube. The light emitting tube includes a middle section that is elongated in a direction parallel to the window width with a length at least equal to the maximum extent of the window width. The light emitting tube includes two boundary sections between which the middle section extends. The two boundary sections have bent ends connected to the middle section at ends thereof, respectively.

Abstract: An image formation apparatus comprises a drawing instruction analyzer which stores the drawing position and the drawing area size of a display list into a list table when the display list is created and a band distributing unit which references the list table after the display lists for one page are created, temporarily determines the height of each band, calculates the total of the drawing sizes of the display lists included in the band height, determines the band height so that the total is equal to or smaller than a predetermined threshold and, based on the determined band heights, distributes the display lists for one page to a plurality of bands.

Abstract: A display apparatus for displaying an image having gradation represented by subfields. The display apparatus includes a display panel, a circuit for outputting information in which a plurality of subfields in one field period is arranged so as to have first plural array portions where allotted light emitting weights increase gradually and second plural array portions where allotted light emitting weights decrease gradually, and a driver for forming a drive signal based on the information and for outputting the drive signal to the display panel.

Abstract: A photographic printer that uses a plurality of small CRTs, or multiple image segments displayed on a single CRT, to print wide format images. Within the printer, the multiple CRTs are positioned adjacent one another and display through lenses so that image segments displayed by adjacent CRTs join one another. The image segments of the single CRT also display through lenses, or mirrors and lenses, that join the segments. The printer may decompose each line of the image into horizontal image segments, or the printer may receive each image segment from a host computer system, and the printer displays the image segments on the CRTs such that they are exposed joined with one another on the photographic media. The printer also contains a closed loop calibration system to adjust the length of each image segment.

Abstract: In a color image display apparatus, assuming that time response characteristics of light emission by red, green and blue light emitting cells have values TR, TG and TB, the difference between the values TR and TG is less than that between the values TR and TB and that between the values TG and TB. The apparatus has a subfield arrangement including a portion where a light emitting weight gradually decreases and a portion where the light emitting weight gradually increases, or a subfield arrangement to obtain a plurality of light emission peaks in one field.

Abstract: A cathode ray tube package includes a cathode ray tube assembly and a housing assembly including a deflection coil and/or at least one focus coil. The cathode ray tube assembly includes a collar (31) aligned with the electron beam, being arranged to mate with a mounting collar (41) carried on the housing assembly. The provision of the collar (31) enables the cathode ray tube assembly to be easily replaced at the end of the cathode ray tube's life within the housing assembly without the need for realignment of the coils.

Abstract: The present invention is a method and apparatus for digitizing film frames. The invention utilizes different colored strobe lights housed in an integrating sphere, instead of the prior art filter and shutter mechanism. The invention's control system flashes each strobe light in sequence for a predetermined time to expose a film frame to various color components. The various color components of the film frame are projected onto a CCD array with the aid of a lens. Each strobe light is flashed at a desired frequency and for the predetermined time in order to saturate the CCD array with the component of light corresponding to that strobe light. The color data corresponding to each color component are passed to digital signal processors for processing and storage. In one embodiment of the invention, the strobe lights are red, green, and blue strobe lights.
